what about greasing under the cpu?

[Mhypertext]

are u supposed to pack grease under the cpu and on the pins

if so why do som thing like that

 

[ThePunkGeek]

umm no you don't need to do anything like that.

 

[nihili]

The only reason for doing anything remotely like that is if you are using extreme cooling and are worried about condensation. If you're using air or water to cool, there's no point.

Seems to me you'd be taking a huge chance at shorting out that cpu. From past experience (someone else that I was watching!) yeah, that is a bad thing to do.

Unless of course your goal is to create smoke.

 

[Neco]

you won't short anything if you use regular good old white grease as far as I know.


but unless you are using a peltier or vapochill or chilled water, etc....

there is no reason in the world to do this

I take it this is done as mentioned above to keep condensation down? Is it really that big of a problem with water cooled systems, or just the pelts?

You only need that if you're using a pelt or some other refrigeration device. Normal air or water cooling won't bring the temperature below ambient, so condensation isn't a concern.

if you plan on doing, say a dual, tri, or quad peltier system, then use, grease that baby up, but other that that, you shouldnt have to, with a single pelt, just put some of that foam padding around the cpu

I used thick masking tape covering the socket and the CPU, just exposing the die. Thinking of using insulation tape or double-sided tape (padded)

I'll keep that in mind when I decide on which way I want to go with the cooling, I'm just using the factory amd hs/fan right now. I'm leaning mostly towards water, since I read a post last night where someone used a fish tank for a res.

That's right up my alley. I got a couple of spare 10gal tanks laying around (aquariums are another hobby) And if I want to get serious I might just empty out a 29gal and get a used tank chiller on the cheap. 29 gal of 35F water out to keep that cpu cool!

If your going for an open fish tank setup I hope you like the smell of bleech, or some other mild detergent to keep the water clean.


Also make sure you get an all copper system, so you don't have that battery effect with alum/copper.

cause then you'd prolly end up needed some stinky chemicals

REAL stinky, knock you out nearly kill you stinky, heh...

Actually I was thinking of using some plastic tubing that I have on hand. And as far as chemicals, I was hoping to avoid those by using some of the filters that I already have for the tanks.

I can filter all Kinds of stuff with them, ain't nothing much stinkier than a fish tank thats been neglected to the point where the filter sys. fails though. Run you right out of the house..........

i heard with peltiers or any super cooling your supposed to use dielectric grease or petroleum jelly (vasoline)

The dialectric grease I would possibly use, (once confirmed here) but I'm not so sure about vasoline. Seems to me it might just be a little on the conductive side. I could be wrong, but I'm sure not gonna spread vasoline on my spark plugs just to find out.

What would the neighbors think of me then? My rep might actually improve..

 

[ptcg]

I used dielectric grease in the empty space in the center of the CPU socket, as well as in the socket itself (to protect the CPU pins). I also put some on the exposed electrical points on the top of the CPU.. Works like a charm..

Also, from what I've heard, vaseline tends to turn yellow, and get runny.. I wouldn't use it.

My air-cooled Peltier HSF's used to blow downwards (as per the tip on the front page) and the system temp tends to be a bit high. I changed the direction today and let it blow upwards and carry the heat outside the case immediately. It worked well and the temp dropped quite a lot. Then after five or six hours the system tends to hang soon after boot up, even the temp was low. After a few times I disembled the set-up and found water drops on the cpu (I used masking tape to seal the CPU/socket) and on the cold plate (I also used masking tape to seal the coldplate and the peltier). Apparently water vapour slip inti the area between the coldplate and around the die. But why did the system hang? Because the water droplet short the circuit? I just switched back to non-Peltier so looks like there is no permanent damage...

Fortunately(?) I am using desktop case so the water just stayed on the horizontal surface on the CPU...

I've always wondered about this grease your are talking about. I have a lot questions about it, so if anyone could give me a link to an article about it, where they explain some about it.
